Abstract: 1,104,592. Thermo-copying apparatus. G. RITZERFELD. July 15, 1966 [Aug. 4, 1965], No.31860/66. Heading G2A. Thermo-copying apparatus comprises an infrared radiator 3 combined with a reflector 4; a fan 10; means 7, 8 forming a guide channel 6 for the copy material; a fixed heat resistant quartz glassplate 5 positioned with one of its sides flush with one side of the channel 6; and a resilient pressure roller 9 arranged on the opposite side of the plate to the reflector, the roller being deflectable towards and away from the plate 5 for effecting intermittent contact between the roller, inserted copy material and the plate. Copy material is inserted at E within a suitable protective envelope, the leading end of which closes a switch 13 to switch on a driving motor 28 and the fan 10. The motor 28 is mounted between a pair of two armed levers 26, 27 pivoted at 22, and provides a counterweight for the roller 9 also mounted between the levers 26, 27. Further insertion of the screen closes a switch 16 to start the radiator 3 and an electromagnet 37 movement of the armature of which causes a locking pawl 30 to release the levers 26, 27 to pivot upwards under spring action and bring the roller 9 into contact with the screen so as to feed it past the plate 5. The radiator 3. has by now reached the required temperature and images the thermally sensitive layers of the copy material into the screen, the leading edge of which next closes a switch 19 in parallel with the switch 13. When the trailing edge of the envelope clears the switch 13 nothing happens, and as it clears the switch 16 the radiator 3 and electromagnet are disconnected, thereby bringing the pawl 30 into contact with a nose 29 of the lever 26, and causing the levers 26, 27 to return to the position shown after a short interval sufficient to feed the trailing edge of the screen past the plate 5. The trailing edge then clears the switch 19 and the motor 28 and fan 10 are switched off. In another embodiment Fig. 7 (not shown) the plate (5) has a plano-convex cross-section, the motor (61) is rigidly mounted, and the roller (19) is mounted between levers (52), (53) pivoted about a shaft (55) fixed in the apparatus. In a further embodiment Figs. 8, 9 (not shown), the roller (9) is mounted above the channel (6) and the fan, radiator, reflector and motor (95) are mounted below the plate (5), the roller being held away from the plate by means of an electromagnet (83), but introduction of copy material de-energizes this electromagnet and energizes an electromagnet (84) to deflect levers (77), (78) and bring the roller into contact with the plate. Various shapes of quartz glass-plates may be used.

Abstract: 506,892. Thermally-actuated valves. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 10, 1938, No. 32651. Convention date, Nov. 12, 1937. [Class 135] [Also in Group XXXVII] A thermally-actuated switch or valve comprises a bulb 16 containing an expansible fluid which act through bellows 16a on a bolt 21 to move a rod 29 to the right so that a collar 42 on the rod allows a lever 54d to turn about 55 and allow arm 47 to move to the off position shown under the action of a compression spring 53, a snap-action being provided by a bowed spring 66. The arm 47 is made bimetallic to compensate for ambient temperature changes of the bellows. The operating temperature is varied by screwing the rod 29 into and out of bolt 21 and for this purpose the end 32 of rod 29 has a splined connection with a bushing 31 rotatable by a graduated knob 58. The bellows and bulb are completely filled with fluid at the minimum operating temperature, e.g. 250‹ F., and sealed by a plug 75. At this temperature, the end of the bellows abuts against the end of the surrounding casing 18. Thus if the knob 58 is turned to a position corresponding to a lower temperature, the bellows are unable to follow and so the switch or valve remains permanently in the off position. Specification 461,119, [Group XXXVII], is referred to.

In a device which may form part of a resonant relay a deflectable member is magnetically coupled with an oscillatable element so as to move in relationship with the amplitude of the oscillations. In the relay shown in Figs. 1, 2 and 3 the coil 11 of a tuned circuit 11, 12 energizes a core 10 to vibrate a tuned magnetic reed 15 biased by a permanent magnet 13. The deflectable member 18 of magnetic material carries a contact 23 and is pivoted at its centre at 19 below the centre line 2-2 of the reed 15 in the rest position. Owing to its inertia the member 18 does not follow the oscillations of the reed 15 but moves in proportion to the amplitude of the oscillations. Alternatively (Fig. 5) two reeds 15, 15<SP>1</SP> may be provided, the reed 15 being arranged to vibrate at the selected frequency and the reed 15<SP>1</SP> at a frequency near that of reed 15. The respective deflectable members 18, 18<SP>1</SP> move in accordance with the amplitudes of vibration of the reeds 15, 15<SP>1</SP> so that the closing of contacts 22, 22<SP>1</SP> is only achieved by a signal of the selected frequency and amplitude. In Fig. 7, L-shaped magnetic deflectable members 18, 18<SP>1</SP> are carried on centrally-pivoted discs 26, 26<SP>1</SP> which also carry contacts 22, 22<SP>1</SP> and the magnetic coupling is assisted by permanent magnets 25, 25<SP>1</SP> with pole faces facing members 18, 18<SP>1</SP> and of a polarity opposite to that induced in the reeds 15, 15<SP>1</SP> by the magnet 13.
